LabVIEW
Voice Recognition with LabVIEW and Windows Vista
As for step 3, think about using System.Speech.Synthesis to have the program reply with voice confirmation.Message Edited by FMonkey on 09-20-2007 11:32 AM
I worked on this, but I couldn't get the recognized string. I think its because I am not %100 on LabVIEW yet and I have never worked with the .NET APIs
. I have
attached my project file as a zip, now if I could get the computer to
say the recognized string instead of my "help me please" I think I can
manage the event/case structures for the actual work being done for
each command.Thankx,
Help Me Please!
HoSsEin,
Follow the diagrams I provided in previous posts. I've modified your project (see attached):
1. Added a “main.vi” that looks
like post 12.
2. Changed your callback to look like
“call” from post 5.
3. Changed SR to “init” from post
5.
I don't have Vista on my main computer
(thankfully 
). I hope there are few bugs. If you want to have
something spoken other than the recognized text, perhaps a case
structure within the event structure. Also, it is advisable to close
your references and handle erros properly.
FMonkey,
This is great! I really appreciate your help ... thx.
I ran it on my XP (after installing speech SDK 5.1) and it actually works ....
but it is slow and shuts down LabVIEW frequently 
I guess the part that I did have issue with was the following (picture).
What is happening there (just so that I know)? I know there was a
"string refnum" that was pointing to the "spoken
text". Can you explain how we take the string from that refnum?
Hi HoSsEin,
I will try to give a short explanation without tripping over the proper terminology. Your best bet is to do a little bit of reading on:
1. References
2. Property Nodes
3. Invoke Nodes
Try a LabView manual or some internet searches. Perhaps the following article:
http://wiki.lavag.org/Control_References
An attempt at an explanation:
You can change the value of a variable (in this case a string control):
By either writing something to a “local variable”
Or by accessing the variable by reference and changing its “Value” Property (more precisely Value(sgnl)).
There are reasons for one approach over the other, but suffice it to say, the latter approach is used by callback vis. There may be a more simple solution to the whole thing, but I will let others advise.
